Alstroemeria plant named Stabec

ABSTRACT

A new and distinct Alstroemeria plant producing flowers having outer petals with light red to deep pink coloration on a white background and inner petals with similar color but additionally including greyed red spots on a yellow background.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria originated as a seedling by crossing as seed parent an unreleased seedling identified as R1684-1 and as pollen parent an unreleased seedling identified as 87G1069-21 among my collection of Alstroemeria seedlings maintained under controlled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer, The Netherlands for developmental purposes. The varietal denomination of the new variety is `Stabec`.

The first act of asexual reproduction of `Stabec` was in Aalsmeer, The Netherlands by propagation by dividing rootstocks. Asexual reproduction through successive generations has demonstrated that the combination of characteristics as herein disclosed for `Stabec` are firmly fixed and retained through successive generations of asexual reproduction.

`Stabec` has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Stabec`, are a colorful combination of outer petals having light red to deep pink coloration on a white background. Inner petals exhibit similar light red to deep pink coloration against a white background and also display greyed purple spots on a yellow background.

The plant produces numerous flowering stems, which is a desirable characteristic in a cut-flower variety. The flower-bearing stems are long, strong and of excellent quality. It has been established that `Stabec` grows productively under greenhouse conditions. The variety is reproducible both by division of rhizomes and by tissue culture.
